In-game footage of Gran Turismo 6 at Sony's E3 booth

E3 2013 - We got a chance to stop by Sony's E3 booth where the PlayStation 4--and PlayStation 3--have taken center stage. Sony set up a massive group of Gran Turismo 6 demos featuring a giant TV, steering wheel, and pedals. We took the opportunity to record some other people playing so that you can see the new Gran Turismo 6.
